The apical triporate, and zonosulcate pollen of Areca are described, as well as examples of mono- and trichotomosulcate pollen within the genus. The sub-apical distal triporate pollen of Sclerosperma gilletii and S. mannii are described. Notably, in Sclerosperma pollen, aperture position at...
(b) Opened male inflorescence with abundant pollen. A typical female flower (gynoecium) has a small cup-shaped calyx tube formed from three outer perianth segments. It has three inner perianths, which are small and circular, and are closely appressed to the three carpels of the superior ...
Each male inflorescence produces a large quantity of pollen, averaging 30 g. Each female inflorescence may have from 700 to 1500 flowers, which are receptive for 36 to 48 h after anthesis. The flowers within an inflorescence open sporadically, taking up to 4 weeks between the initial and the...
during the late Cretaceous Period. The first modern species, such as Nypa fruticans and Acrocomia aculeata, appeared 69-70 million years ago, confirmed by fossil Nypa pollen dated to 70 million years ago. Palms
